Load Test — Per-Request Log (CSV)

Three hundred individual request records with timestamp, scenario, status and duration — the raw log a percentile calculation has to be computed from rather than read off. A handful of 4xx and 5xx responses are mixed in so an error-rate calculation has something to find.

Scenario
Compute percentile latencies and an error rate from a raw request log.
Expected result
300 rows parse with numeric duration_ms, and every row whose status is not 200 counts toward the error rate rather than being filtered out.

What is a .csv file?

CSV (Comma-Separated Values) is a plain-text tabular format where rows are lines and fields are separated by commas, with quoting rules for values that contain delimiters, quotes, or newlines. It has no formal type system and depends on encoding and dialect conventions. It is the most portable format for tabular data exchange.

How to use this file

Use an example CSV to test parsers against quoting and embedded-delimiter edge cases, header handling, encoding detection, and import pipelines into databases or spreadsheets.

How to use this file for testing

“Load Test — Per-Request Log (CSV)” is a deterministic Novus Examples fixture for Performance testing, CSV parsing, Time-series data. Documented size, row-count, duration, and resolution ladders for measuring parser, renderer, converter, and upload performance without relying on private production data.

Documented properties for this file: seed 61200 · 300 rows · 8 columns · LF. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.

Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.

Test and coverage reports document their totals (suites, cases, passes, failures, skips, covered lines) in the spec table. Point your CI dashboard, coverage gate, or report converter at the file and assert those counts survive; format twins carry identical numbers so a conversion can be scored exactly.

import pandas as pd

df = pd.read_csv("load-test-requests.csv")
